Intersesting where the 'occult' or magic comes from in these British Horrors. Although the horror in Quatermas and the Pit comes from Mars, its manifestation is distinctly urban. Compare with the Wicker man, where the 'horror' comes from the rural. In the Wicker Man the ocult seems also to be a form of expertese, again a common theme in British Horror, especially where the source of the occult is male. Suimmerisle is also a libertine. Where the source is female, then these tend to be less intellectual. Interesting also that both are horrors by the skin of their teeth if at all- the Sci-fi element in QATP is dominant, and I'm not sure about TWM. I think it's more of a detective yarn that goes adrift. Now, for real fear- how about The Stone Tape- also a Nigel Kneale. Anyway praise be that it's not all documentary realism.
